NUT-LOCK.

To all whom it may concern:

Be it known that I, ALBERT DILLON, citizen of the United States, residing at Aitch, in the county of Monroe and State of Ohio, have invented certain new and in Nut-Locks, which the following is a specification.

This invention relates to new and useful improvements in nut locks and it has particular reference to a nut lock of that type which includes a removable key carried by the bolt and formed for engagement with grooves cut into the bolt and nut.

It is a further object of the invention to facilitate the locking and unlocking of the nut without damage to either of these members, and thereby to provide for the repeated use of both the bolt and nut.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the ac companying drawings, described in the following specification and then more particularly pointed out in the claim which is appended hereto and forms a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation of a nut lock constructed in accordance with my invention; Fig. 2 is a section on the line 33 of Fig. 1; Fig. 3 is a section on the line 22 of Fig. 1; Fig. 4 is a detail elevationof the locking key or member, partly broken away; and Fig. 5 is a longitudinal sectional view of a portion of the bolt and key illustrating the manner in which the latter is retained in proper place.

Referring now to the drawings, wherein is illustrated the embodiment of my invention the numeral 1 designates a bolt of ordinary construction having the usual threaded portion 2 formed upon one end thereof. Diametrically opposite grooves 3 are formed within the threaded portion 2 of the bolt the said grooves being connected by a transverse groove 3 extending across the outer end of the bolt shank 1.

Nuts

4 and 5 respectively are adapted to be threaded or screwed upon the threaded portion 2 of the bolt and locked thereupon in a manner to be hereinafter fully described. Oppositely disposed grooves 6 and 7 are formed re Specification of Letters Patent.

spectively within the

nuts

4 and 5,the said grooves, when the nut is threaded over the shank 2 of the bolt, adapted to receive a key member 8 which is in turn inserted or forced into the grooves 30f the bolt, the edges of the said key projecting'beyond the periphery or outer face of the bolt shank. The said key member 8 is split centrally from its inner end thereby forming arms 8 disposed to straddle the threaded portion 2 of the bolt; the connecting portion of the key designated 9 fitting within the transverse groove 3 of the said bolt.

For the purpose of locking the'key 8 against accidental removal, a cotter pin 9 is provided, one portion ofthe pin being in serted or forced into an opening 10 formed Within the extremity of the bolt shank so as to extend therethrough in a direction transverse to the groove 3 above mentioned, that portion of the key member fitting within the said groove 3 having an opening 11 formed therein adapted to register with the said opening 10 as illustrated to advantage in Fig. 5 of the drawings. A larger opening 12 is formed within the key member 8 adjacent the opening 11, through which the other portion of the cotter pin 9 is inserted, this arrangement of the pin with respect to the key and bolt locking the former against lateral as well as longitudinal movement independent of the bolt itself.

The grooves 6 and 7 of the nuts are formed in uniform spaced relation and extend throughout the entire length of the central bore or opening of the said nuts, this arrangement of the grooves permitting the key member 8 to be placed and removed after the-said nuts have been properly ad jousted upon the threaded portion 2 of the olt.

It will be seen from the above, taken in connection with the accompanying drawings that the removal of the pin 9 andthe withdrawal of the key member 8 from thevslots 3 of the bolt shank, will permit the nuts 5 and 6 threaded thereon to be either entirely removed or freely adjusted as occasion deembodiment of my invention and that various minor changes in details of construction, proportion and arrangement of parts may be made Within the scope of the appended claim and Without sacrificing any of the advantages of my invention.

Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent, is

In a nut lock, a grooved bolt, a grooved nut, said grooves forming key Ways, a substantially fiat locking key comprising a head portion having two openings formed therein, arms extending therefrom in parallel spaced relation, said arms fitting said Ways,

said head portion fitting a transverse groove connecting said bolt grooves, and a locking pin of the cotter type, one of the extensions of which is insertible Wi thin an opening of the bolt and one of the openings of said head, the other of the said extensions being insertible Within the other of the said head openings exteriorly of the bolt, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of tWo Witnesses.
